Underground restaurant

An underground restaurant, sometimes known as a supper club or closed door restaurant, is a social dining restaurant operated out of someone's home, generally bypassing local zoning and health-code regulations. They are usually advertised by word of mouth or unwanted advertising. Websites such as BonAppetour have been created to help people find and book these restaurants.

Depending on the area's law, the establishments may be illegal, even though they have been around for decades. They are becoming increasingly popular in the U.S. and internationally, including Cape Town and the Netherlands, where they are known as 'huiskamer restaurants' ('living room restaurants').
